Main features:

1, in order to effectively control the stability of the test pressure value, keep the test pressure control in up to + 2%, lower end control at 1%, the microcomputer control blasting pipe hydrostatic testing machine for every all the way from original professional high pressure solenoid valve in Germany, with fast booster, slow intermittent fill the function of the pressure and discharge pressure, thus good achieve rapid pressure rise, slow filling pressure, accurate display pressure numerical value to 0.001 MPa, when rapid unloading end of the test, the test pressure value always stay within the set value.

2, in order to solve the test pressure value and the interface shows hysteresis, the pressure of the pressure sensor sampling frequency of 0.02 seconds, improved the overall signal response speed, control precision and reliability of long-term work, the more sensitive, more accurate.

3. The microcomputer control pipe material static hydraulic blasting test machine also has the blasting function to realize the double function.

4. Multiplexing and multi-station, each road test can be done at the same time without impact. The test machine has functions of operation, stop, leakage and fracture identification.For example, the solenoid valve can be closed automatically when the sample is damaged. The other roads are not affected as usual.The experimental data and graphics are automatically recorded and stored in the computer.

5, electrical components imported components or domestic famous brand products, such as: Germany GSR solenoid valve, the United States imported from three plunger pump, Germany wheeler circulating pump, pressure sensor, from the control principle and the quality of the electrical components ensures the accuracy and stability of the tester.

6. The temperature control scope is wide: the microcomputer control tube hydrostatic blasting test machine can do 20-95 test, the heating and cooling speed is fast, the water tank adopts stainless steel not easy to rust, and the insulation performance is good.It also has the extracorporeal circulation device, which guarantees the reliability and stability of the test.

7. The professional test software is mature and stable without defects. It can display the pressure curve of each road in real time, and the real-time data display can be printed and programmed test report.

8. Type A clamp, O type seal, convenient sealing, good sealing, easy to operate.

9. Use accumulator to fill pressure, realize passive control, reduce the working time of the motor and pressure system, improve the service life of the pressurized system, and also ensure the pressure accuracy.

10. The machine has the function of power loss protection, and it is only necessary to adjust the last test after the power of the hydraulic blasting test machine of pipe material to continue the experiment, reduce the working strength and improve the working efficiency.

11. The hydraulic control method is adopted to improve the stability and reliability, and the pressure speed and control accuracy are further improved.
